Kelly Osbourne has spent more than two decades navigating fame in public, but the past year and a half has been the most difficult and closely watched period of her adult life. Following the death of her father, rock legend Ozzy Osbourne, in July 2025, Kelly has faced the end of her engagement, intense public scrutiny over her appearance, and a long, openly discussed process of grief and recovery.

This article is a complete, current and carefully sourced account of Kelly Osbourne’s personal life: her relationships, motherhood, family life, weight loss history, health and recovery journey, and the latest confirmed developments from 2026. It works as a standalone resource, though readers wanting a fuller account of her career and early life may also find our companion biography article useful. Wherever information is based on media reports, estimates or public speculation rather than something Kelly or her family have confirmed, that distinction is made clear.

Kelly Osbourne’s Personal Life Quick Facts

Kelly Osbourne’s Personal Life

Away from her television and fashion work, Kelly Osbourne’s personal life has centred on motherhood, family, sobriety and, more recently, grief. She has built a public reputation for being unusually candid about difficult subjects, choosing to address rumours and criticism directly rather than staying silent, a pattern that has continued through the hardest period of her adult life following her father’s death.

Relationships and Partner

Kelly’s dating history includes a previous engagement to model Luke Worrall and a relationship with chef Matthew Mosshart, though her most significant and long term relationship in recent years was with Sid Wilson, a member of the American metal band Slipknot.

How Kelly and Sid Wilson Knew Each Other

Kelly and Sid first connected around 1999, when Slipknot performed at Ozzfest, the touring festival co-founded by her parents. The pair developed a friendship that lasted more than two decades before turning romantic.

When Their Relationship Became Romantic

In February 2022, Kelly confirmed on Instagram that her long friendship with Sid had developed into a romantic relationship, writing that after 23 years of friendship, she could not believe where they had ended up and calling him her best friend and soulmate.

Their Son

Kelly and Sid welcomed a son, Sidney, in November 2022, shortly after publicly confirming their relationship

Their Engagement

Sid proposed to Kelly in July 2025, during Black Sabbath’s farewell concert in Birmingham, the same show that marked one of Ozzy Osbourne’s final public performances. Both Sharon and Ozzy Osbourne were present to witness the proposal.

Major Public Appearances Together

The couple made several notable public appearances together, including at the 2026 Grammy Awards on February 1, which turned out to be their final public outing together as a couple. At the Grammys, they were present for a musical tribute to Ozzy Osbourne performed by artists including Post Malone, Slash and members of Guns N’ Roses.

Reported Relationship Developments in 2026 and Their Split

In March 2026, multiple entertainment outlets reported that Kelly and Sid had ended their relationship and called off their engagement, roughly seven months after Sid’s proposal. Sources cited by entertainment publications described a difficult period leading up to the split, coinciding with Kelly’s grief following her father’s death. One insider told a publication that Kelly was reportedly unhappy in the relationship for some time before the split became public.

In August 2026, the situation became more public when Sid Wilson was reportedly removed from Slipknot after 28 years with the band. TMZ reported that Sid was informed of the decision on July 31, 2026, though no official reason was given at the time. Slipknot later confirmed the split from Wilson in a statement released around August 15, 2026, without publicly detailing the reasoning. Some entertainment outlets, citing unnamed sources, reported that the decision followed concerns among bandmates about Sid’s behaviour, though this has not been confirmed in an official band statement.

Following the reports of Sid’s departure from Slipknot, Kelly addressed him directly and pointedly on her Instagram Stories in early August 2026, telling him to take responsibility for his actions and referencing outstanding matters including the return of her belongings and child support for their son. She did not go into further detail about the reasons for their split in these posts.

What Has and Has Not Been Officially Confirmed

• Confirmed: Kelly and Sid Wilson were in a relationship from 2022 to 2026 and share a son, Sidney.
• Confirmed: The couple became engaged in July 2025 and the engagement ended by March 2026.
• Confirmed: Slipknot officially parted ways with Sid Wilson in August 2026.
• Not officially confirmed: The exact reason for Kelly and Sid’s split, and the exact reason for Sid’s departure from Slipknot, have not been officially detailed by either party or the band.
• Not officially confirmed: As of this writing, Kelly has not publicly confirmed a new relationship.

Children

Kelly has one child, her son Sidney, born in November 2022. She has spoken about motherhood as one of the most grounding and meaningful parts of her adult life, particularly during the difficult period following her father’s death and the end of her engagement. In line with responsible reporting on children of public figures, this article does not include further private details about Sidney beyond what Kelly has chosen to share publicly.

Family Life

Kelly’s family life has been defined heavily by the Osbourne family’s shared grief since Ozzy Osbourne’s death in July 2025. Ozzy, the Black Sabbath frontman, died at age 76 at his family home in Buckinghamshire, England. His death certificate, filed in London by his daughter Aimee Osbourne, listed the causes of death as out of hospital cardiac arrest, acute myocardial infarction, coronary artery disease and Parkinson’s disease with autonomic dysfunction. Ozzy had publicly disclosed his Parkinson’s diagnosis in 2020 and had spoken openly in his final years about the toll it had taken on his mobility.

His death came just weeks after his final public performance, a widely covered farewell concert with the original Black Sabbath lineup in Birmingham on July 5, 2025. The family held a public funeral procession through Birmingham on July 30, 2025, followed by a private funeral at the family’s Buckinghamshire estate, where Ozzy was buried near a lake on the property, reportedly in line with his own wishes.

Since then, Kelly, her mother Sharon, and her siblings Jack and Aimee have continued to appear together publicly at events honouring Ozzy’s legacy, including award ceremonies, and have discussed their grief openly on The Osbournes Podcast. Sharon Osbourne has been especially vocal in defending Kelly against online criticism during this period, including in television interviews.

Weight Loss Journey

Kelly Osbourne’s relationship with her weight and body image has been a recurring, well documented part of her public life since her teenage years, long before her more recent health related weight changes became a talking point in 2025 and 2026.

Teenage Body Image Struggles and Public Scrutiny

Kelly has said that scrutiny of her body began when she was still a child, appearing on The Osbournes. In a 2024 episode of The Osbournes Podcast, she recalled being told by her own team that she was too fat for television. She has also spoken about being bullied over her weight as a teenager, describing being told by strangers to stop eating and crying over the comments she received.

Gastric Sleeve Surgery

In August 2020, Kelly publicly disclosed that she had undergone gastric sleeve surgery approximately two years earlier, in 2018. She revealed this on the Hollywood Raw podcast, explaining that the procedure removed roughly 80 per cent of her stomach.

She described the decision as connected to her broader recovery from addiction, explaining that after getting sober in 2017, she began overeating as a replacement coping mechanism and gained weight rapidly as a result. She said the surgery helped reduce cravings tied to emotional eating, though she was clear that it was not a simple fix. In her own words at the time, she said the surgery was not a quick fix and that anyone considering the procedure needed to be prepared to also change their diet and exercise habits, since the surgery alone only moves a person in the right direction.

Kelly has been reported to have lost approximately 85 pounds, or around 38.5 kilograms, in the aftermath of the surgery. She has said she required a full year of therapy to prepare herself for the procedure before undergoing it.

Lifestyle Changes Following Surgery

Following her 2018 surgery, Kelly has spoken about adjusting her portion sizes and working on the underlying emotional eating patterns connected to her addiction recovery. She has described the surgery as one part of a much broader lifestyle and mental health effort rather than a standalone solution.

Recent Weight Changes and Public Discussion (2025 to 2026)

Following her father’s death in July 2025, Kelly’s physical appearance changed again, and this second phase of change is distinct from her earlier, planned 2018 surgery. Kelly has been clear that this more recent change is connected to grief and a period of poor health rather than a deliberate weight loss effort.

Public attention to her appearance intensified sharply after she appeared at the 2026 BRIT Awards in late February, where she and her mother Sharon accepted a lifetime achievement award on Ozzy’s behalf. Photos and videos from the event circulated widely online, prompting a wave of comments, some sympathetic and many critical or alarmed, about her noticeably slimmer appearance.

Kelly addressed the criticism directly on Instagram Stories, writing that there is a special kind of cruelty in harming someone who is clearly going through something and describing the comments as kicking her while she was down. This was not the first time she had responded to this kind of scrutiny. In December 2025, she had already addressed similar comments in a now deleted Instagram video, telling critics who suggested she was ill or should stop using Ozempic that her father had just died and that she was doing the best she could.

In an August 2026 interview with Hello! magazine, her most detailed public statement on the subject, Kelly said plainly that she had not been well, describing the period as the hardest of her life and confirming that she was, in her words, so sick during the months following her father’s death. She said she is getting a lot better and credited therapy and her support system with her improvement, while stressing that recovery is a slow, ongoing process rather than something resolved quickly.

What Kelly Has Said About Ozempic Speculation

Online speculation has repeatedly linked Kelly’s recent, more dramatic weight changes to Ozempic or similar weight loss medications. Kelly has not confirmed using Ozempic or any comparable medication. She has directly and publicly pushed back against this assumption, most notably in her December 2025 Instagram video, where she addressed commenters telling her to get off Ozempic by explaining that her weight and appearance were connected to her father’s recent death and her overall wellbeing, not to any specific medication. As of this writing, there is no confirmed public statement from Kelly, her representatives or her family that names a specific medication or medical treatment behind her 2025 to 2026 weight changes.

Diet and Lifestyle

Publicly, Kelly has discussed general dietary adjustments tied to her 2018 gastric sleeve surgery, including smaller portions and a focus on more nutrient dense foods. She has not disclosed a specific, current diet plan, calorie target or meal structure connected to her 2025 to 2026 recovery period. Her public statements during this period have focused far more on therapy and mental health than on any particular dietary routine, and this article does not speculate about details she has not shared.

Fitness and Workout Routine

No specific, current workout routine has been publicly disclosed by Kelly during her 2025 to 2026 recovery period. In earlier interviews tied to her 2018 surgery, she referenced general physical activity as part of her broader lifestyle changes, but she has not detailed a specific fitness regimen more recently. Readers should treat any specific workout claims found elsewhere online as unverified unless directly sourced to Kelly herself.

Health History

A Careful, Factual Overview

Kelly Osbourne has been unusually open about her health history over the years. The following is a factual summary of what she has publicly disclosed, clearly separated by topic and time period.

Addiction and Recovery

Kelly has spoken extensively about her history with prescription drug and alcohol addiction, which she has linked back to being prescribed liquid Vicodin at age 13 following a tonsillectomy. Her substance use escalated during her teenage years and into early adulthood, coinciding with the pressures of being a young, constantly scrutinised public figure.

Sobriety

Kelly achieved sobriety in 2017. She has spoken about this milestone publicly on multiple occasions, describing it as a significant turning point in her life.

Publicly Disclosed Relapse

In April 2021, Kelly disclosed on Instagram that she had relapsed after nearly four years of sobriety. She described the experience honestly, stating that she was not proud of it but was working to get back on track, and reaffirmed her commitment to ongoing recovery, describing it as a one day at a time process. She has since referred to herself as sober in subsequent interviews and public statements.

Lyme Disease

In her 2017 book, There Is No F*cking Secret: Letters From a Badass Bitch, Kelly revealed that she had been diagnosed with stage three neurological Lyme disease after experiencing unexplained symptoms for some time. She has since described the diagnosis as something that almost killed her and has spoken about it publicly as a serious, often misdiagnosed illness, distinct from her later, unrelated weight and health discussions.

Gastric Sleeve Surgery

As detailed above, Kelly underwent gastric sleeve surgery in 2018, which she disclosed publicly in 2020, describing it as a significant and positive decision in her recovery from emotional eating.

Recent Grief Related Wellbeing (2025 to 2026)

Following her father’s death in July 2025, Kelly has described experiencing a period of serious physical and emotional decline, at one point describing herself as so sick, though she has not disclosed a specific medical diagnosis connected to this period. She has stated that she is improving as of her most recent public comments in August 2026, crediting therapy, family support and time.

Mental Health and Recovery

Kelly has spoken candidly about the role therapy has played throughout her adult life, both in her earlier recovery from addiction and in her more recent grief following her father’s death. In her August 2026 interview with Hello! magazine, she explained that therapy has helped her understand behavioural patterns that trace back to her childhood, describing recovery as a lifetime of work rather than something that can be resolved after a single session.

She has also spoken about the importance of her support system during this period, noting that grief tends to reveal who genuinely stands by a person, since some friendships fall away during difficult times while others deepen. She has credited her mother, close friends and her son with giving her reasons to continue moving forward.

Recent Public Statements

Some of Kelly’s most significant recent public statements include the following, each addressing a different aspect of her recovery and the scrutiny she has faced.

On the criticism following the BRIT Awards: she wrote on Instagram that there is a special kind of cruelty in harming someone who is clearly going through something and that she should be commended simply for getting out of bed and facing her life.

On being told to stop using Ozempic: in December 2025, she responded to critics by explaining that her father had just died and that she was doing the best she could, without confirming or discussing any specific medication.

On her overall health in August 2026: she told Hello! magazine that she had not been well, that she is getting a lot better, and that recovery is a slow process that will take a lifetime of ongoing work.

Public Reaction

Public reaction to Kelly’s appearance and health disclosures since 2025 has been divided. A significant portion of social media commentary has expressed alarm or made critical, sometimes cruel remarks about her weight, including unverified assumptions about medication use. At the same time, she has received considerable public support, both from fans and from her own family. Sharon Osbourne has publicly defended Kelly on multiple occasions, including in television interviews, explaining that her daughter was grieving the loss of her father and was not in a position to simply bounce back to her previous appearance.

This article intentionally avoids repeating the most graphic or cruel comments directed at Kelly online, focusing instead on the substance of the public conversation and her own responses to it.

A Clear 2025 to 2026 Timeline

FAQ

What happened to Kelly Osbourne?

Since July 2025, Kelly has experienced the death of her father, Ozzy Osbourne; the end of her engagement to Sid Wilson; and a period of noticeable weight loss and public scrutiny that she has attributed to grief and being unwell, rather than to any confirmed medical treatment.

Her more recent, 2025 to 2026, weight changes have not been quantified in specific figures by Kelly herself, and she has attributed them to grief and illness rather than intentional weight loss.

Did Kelly Osbourne have weight loss surgery?

What type of weight loss surgery did Kelly Osbourne have?

She had a gastric sleeve procedure, also known as a vertical sleeve gastrectomy, which involves removing a significant portion of the stomach to reduce its capacity.

Final Words

Kelly Osbourne’s personal life over the past year and a half tells the story of a public figure navigating profound loss under intense scrutiny. The death of her father, the end of a long term relationship, and a period of serious personal struggle have unfolded almost entirely in public view, and Kelly has responded not by retreating from that visibility but by continuing to speak directly about what she has been going through.

Her weight loss journey spans two very different chapters: a deliberate, medically supported process in 2018 aimed at supporting her recovery from addiction and a more recent, grief driven period of physical decline that she has been open about without offering false reassurance. Her approach to both her body and her mental health throughout 2025 and 2026 has consistently emphasised honesty over image management, even when that honesty has invited criticism.

As of late 2026, Kelly Osbourne appears to be in a genuine, if gradual, period of recovery. She continues to work, continues to parent her young son, and continues to lean on her family, particularly her mother Sharon, as she rebuilds her personal life after an exceptionally difficult stretch. Her story remains a reminder that public recovery rarely follows a straight line and that the willingness to say so publicly, even when it invites scrutiny, has remained one of the most consistent threads throughout her adult life.
